NFL.com breaks down the Top 15 rookies for 2013 so far. The Cardinals are the only team with two rookies on that list, with Tyrann Mathieu at #5 and Andre Ellington at #13. More details in the link. Can you imagine if Cooper hadn't gone down with an injury? We could have possibly had 3 "Top 15" rookies for all we know. Gotta give credit to Steve Keim on this one.
